Code Review
This pull request refactors the FrontendAgent to focus exclusively on frontend development by removing backend-related prompts and the _generate_backend method. While the changes streamline the agent's purpose, several issues were identified: the new surgical edits instructions in the system prompt conflict with the existing file-saving implementation, numerous unreachable backend template methods remain as dead code, and the docstring incorrectly claims support for self-fix loops that are not implemented in the run method.

The added instructions regarding "surgical edits" and the LocalFileEditTool contradict the current implementation. The _generate_frontend method (line 78) explicitly requests "string content" for file paths, and the run method (line 61) saves this content directly to files. If the LLM follows the system prompt and provides surgical edits (e.g., search/replace blocks) instead of full file content, the resulting files will be corrupted. Furthermore, the FrontendAgent does not have the LocalFileEditTool registered to process such edits.

The refactor to remove dead backend code is incomplete. While the _generate_backend method has been removed, the class still contains approximately 450 lines of backend-specific template methods (e.g., _generate_main_app, _generate_config, _generate_database, etc., starting at line 116 in the full file). These methods are now unreachable and should be removed to fully clean up the FrontendAgent class.

The docstring claims support for "self-fix loops", but the run method implementation (lines 48-63) only performs generation and saving. It does not appear to invoke any linting, fixing, or critique loops (such as the self_critique method defined in BaseAgent).
